Whenever I try to hold and place an oil derrick or train drawbridge or interact with one, the game gets this error:

The mod Cargo Ships (0.2.6) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event cargo-ships::on_player_cursor_stack_changed (ID 31)
Given value has to be smaller than or equal to: 4.29497e+09
stack traceback:
[C]: in function 'newindex'

Please help as I can't use your mod fully with this error.
Is there a way to fix this?

Do you have any other mods installed that increase the reach of your character? That is the most likely cause, and disabling that mod should fix this error. If you can find which one conflicts, them I can look at adding compatibility.

I have a mod called Far Reach and there is another mod that increases reach which is the creative mod but Far Reach isn't enabled though

I can't reproduce this with just Cargo Ships and Creative Mod. I'll need the save file in order to load all the mods and settings to see what caused it.

SOLUTION: You can solve this issue yourself by loading your save, going to Pause menu -> Settings -> Mod Settings and changing Cargo Ships -> "Reach increase when holding offshore buildings" and setting the value to "0" (zero). Then Cargo Ships will not attempt to modify your build reach bonus at all.

Thank you so much! I just tested it and it worked!
